Earlier quoted context omitted.
If we're lucky we can get this kind of outrage built up when it is, and then fix it for everyone. These laws get passed when the innocent victim is a sympathetic white girl, why can't they get repealed when the innocent accused is a sympathetic white boy?
No laws are being rewritten posthumously for 'sympathetic white girl'. There's really no need to inject 'prosecuted white guy' into the conversation.
There are numerous examples of laws that have 'little innocent white girls' as catalyzing moments, to the extent that they are often named after the victims, if only in popular media. Just from the top of my head and a few seconds on google: numerous proposed "Caylee's Laws", Chelsea's Law, Marsy's Law, Jessica's Law, Megan's Law...
There is a metric bucketload of laws named after people here: http://en.wikipedia.org/wiki/List_of_eponymous_laws
I don't really feel like filtering that by "young female victim", it would be too depressing.
